1. Hoʻolauna
Ma ke kahua o ka hoʻomalu ʻana i ka wai ʻoihana, hoʻokani nā kīwaha hoʻomaha, a ʻo ia kekahi o nā mea nui o nā kīwaha hoʻomaha, ʻo ke kūpaʻa ʻana o nā huila kila kila ka mea nui o ka nānā ʻana i ka ʻoihana. Me ka hoʻomaikaʻi mau ʻana o ka pono o nā mea hana a me nā koi paʻa i nā ʻoihana like ʻole, -ka noiʻi hohonu e pili ana i ke kūpaʻa ʻana o nā huila kila kila ma nā kiwi hoʻomaha he mea koʻikoʻi koʻikoʻi koʻikoʻi.
2. Corrosion kū'ē kumu ohuila lima kila kuhiliʻole
ʻO ke kumu i loaʻa ai i ke kila kila maikaʻi ke kūpaʻa ʻana i ka corrosion no ka mea aia ma ka liʻiliʻi he 12% chromium. Hoʻohui ʻia ʻo Chromium me ka oxygen i ka lewa e hana i kahi kiʻiʻoniʻoni chromium -waiwai waiwai nui loa ma ka ʻili o ke kila kila. Hiki i kēia kiʻiʻoniʻoni oxide ke pale i ka hoʻomau ʻana i ka infiltration a me ka oxidation o nā ʻātoma oxygen, no laila e hana ai i ka ʻōpala kuhiliʻole -paʻa a pāʻani i ke kuleana o ka pale passivation, e hōʻemi nui ana i ka hiki ʻana o ka corrosion o ka huila kila kila.
3. Nā mea e pili ana i ka hana anti-corrosion o huila lima kila kuhiliʻole
●Material pono'ī: Okoa ano o ka kuhiliʻole kila, e like me 304, 316, 316L, etc., he okoa corrosion kū'ē . 316 a me 316L kuhiliʻole kila i loko o molybdenum, i mea e oi aku ka maikaʻi i loko o ke kai kū'ē a me ka chloride ion corrosion kū'ē, oiai 304 kuhiliʻole kila i ka maikaʻi corrosion kaiapuni a me ka freshwater kaiapuni.
●E hoʻohana i ka pōʻaiapuni: Inā ʻo ka pahu hoʻomaha i loko o kahi wahi haʻahaʻa i waiwai i ka paʻakai, ka waikawa a me ka alkali a me nā mea hoʻoheheʻe ʻē aʻe, a i ʻole hana ma lalo o ke kiʻekiʻe o ka wela a me nā kūlana kiʻekiʻe, hiki ke hoʻohālikelike i ke kūpaʻa ʻana o ka huila kila kila. No ka laʻana, ma nā kahua o ka ʻoihana kemika a me ka ʻenekinia moana, ʻoi aku ka nui o nā media corrosive, a ʻoi aku ka kiʻekiʻe o ke kūpaʻa ʻana o nā huila kila kila.
● Ke kaʻina hana lapaʻau ʻili: ʻO ka ʻili o ka ʻili o ka huila kila kila, inā he ʻōpala, ke koena o ke koʻikoʻi i ka wā o ka hana ʻana a me nā mea ʻē aʻe e pili ana i kona kūpaʻa ʻana. Inā kūpono ʻole ka mālama ʻana i ka ʻili, hiki ke hōʻino ʻia ke kiʻiʻoniʻoni passivation ma ka ʻili kila kila, a laila e hōʻemi ana i kona kūpaʻa corrosion.
4. Ka helu hihia o ka corrosion ohuila lima kila kuhiliʻolei lokonā noi kūpono
● ʻOihana Kemika: I loko o kahi ʻoihana kemika, ua ʻānai ʻia kekahi mau pahu pani e hoʻohana ana i nā huila kila kuhili ʻole 304 ma hope o ka -pili lōʻihi me ka ʻakika ikaika a me ka pāpaʻi alkali, a hiki i ka huli ʻana o ka huila lima hiki ʻole a hiki i ka ʻōpala a me nā lua ʻino. Ma hope o ka nānā ʻana, ua ʻike ʻia he kiʻekiʻe ke kiʻekiʻe o ka chloride ion i loko o ke kinikini, ʻoi aku ka nui o ka tolerance range o 304 stainless steel, e luku ana i ke kiʻiʻoniʻoni passivation ma kona ʻili.
●Ke kahua ʻenekinia moana: I loko o nā ʻōnaehana pipeline o kekahi mau kahua o waho, ke kū nei nā kiwi hoʻokuʻu lima lima kila kila i nā hoʻāʻo koʻikoʻi. Ma muli o ke kino ikaika o ka paʻakai paʻakai a me ka wai kai i loko o ke kai moana, hiki i nā huila kila kila 304 maʻamau i ka pitting a me ka crevice corrosion, e pili ana i ka hoʻohana maʻamau a me ka palekana o ka pahu pani.
5. Nā ana e hoʻomaikaʻi i ka hana anti-corrosion o huila lima kila kuhiliʻole
●E koho i ka mea kila kuhiliʻole kūpono: E koho i nā mea kila kuhiliʻole me ka pale ʻana i ka corrosion e like me ke kaiapuni hoʻohana kikoʻī a me ka waena. No nā kaiapuni ʻinoʻino, 316, 316L a me nā kila kila ʻē aʻe me ke kūpaʻa ʻoi aku ka ikaika.
●Optimize ili lapaʻau kaʻina hana: Ka hoʻohana 'ana i ka holomua ili lapaau 'enehana, e like me electrochemical polishing a me ka passivation lapaau, hiki ke hoʻomaikaʻi i ka ili hope o kuhiliʻole kila lima huila, hoʻoponopono a hoʻonui i ka passivation kiʻiʻoniʻoni ma luna o ka ili, a laila hoʻomaikaʻi i kona corrosion kū'ē.
● Hoʻolālā kūpono a me ka mālama ʻana: Ma ke kaʻina hana hoʻolālā o ka valve stop, pono e hoʻemi ʻia ka wahi hoʻopili ma waena o ka huila lima a me ka corrosive medium e pale i ka hōʻiliʻili ʻana o ka wai, ka lepo a me nā kūlana ʻē aʻe e pili ana i ka corrosion. I ka manawa like, mālama mau a lawelawe i ka valve stop, wehe koke i ka lepo, nā ʻōpala a me nā huahana corrosion ma ka ʻili o ka huila lima, e nānā i ka corrosion o ka huila lima a lawe i nā ana kūpono.
6. Nā hana ho'āʻo no ka hana anti-corrosion o huila lima kila kuhiliʻole
● Ho'āʻo paʻakai: E kau i ka huila kila kila i loko o ke keʻena hoʻāʻo paʻakai e hoʻohālike i ke kaiapuni kai a i ʻole ka lewa ʻoihana koʻikoʻi, e nānā i kona ʻino i loko o kahi manawa i ʻōlelo ʻia, a e hoʻoholo i kāna hana anti-corrosion ma ka loiloi ʻana i ke kiʻekiʻe o ka ʻino.
●Electrochemical ho'āʻo: E hoʻohana i ka electrochemical workstation no ke ana i ka polarization curve, electrochemical impedance a me nā palena 'ē aʻe o ka kuhiliʻole lima huila i loko o kekahi corrosive medium, i mea e maopopo ai kona corrosion hiki, corrosion o keia manawa nui a me kekahi 'ike, a me ka pololei loiloi i kona corrosion kū'ē.
7. Nā kūlana ʻoihana no ka hana anti-corrosion ohuila lima kila kuhiliʻole
ʻO nā kūlana o ka ʻoihana valve honua a me ka home, e like me ISO 15761 a me GB / T 12235, he koi maopopo no ka pale ʻana i ka corrosion o nā valve stop, me ka pale ʻana o ka corrosion ohuila lima kila kuhiliʻole.Hōʻike kēia mau maʻamau i ka haku mele ʻana, nā ʻano hoʻāʻo ʻana i ka corrosion resistance, nā ʻae ʻana, a me nā mea ʻē aʻe o nā mea kila kila, a hāʻawi i nā kikoʻī a me ke alakaʻi ʻana no ka hoʻohana ʻana i nā huila kila kila ma nā pahu pani.
8. Ke holomua nei ka noiʻi a me ka hana hou i ka hana anti-corrosion okila kohu ʻolehuila lima
I kēia manawa, ʻo ka hui hoʻomaka ʻo Hangzhou Xiaoshan, ke ʻimi mau nei nā mea noiʻi i nā mea hao kila kila hou a me nā ʻenehana lapaʻau i luna e hoʻomaikaʻi hou i ke kūpaʻa ʻana o nā huila kila kila. No ka laʻana, hiki i kekahi mau mea hao kila kila hou ke hoʻomaikaʻi maikaʻi i ko lākou kūʻē ʻana i ka corrosion i loko o nā kaiapuni corrosive paʻakikī ma o ka hoʻohui ʻana i nā mea ʻeleʻele. I ka manawa like, hoʻomau ka hoʻomaikaʻi ʻana o nā ʻenehana lapaʻau i ka ʻili e like me ka nano -coating technology a me ka ʻenehana implantation ion i ka hana ʻana i nā huila kila kila, e hāʻawi ana i nā ala hou e hoʻomaikaʻi ai i ka pale ʻana i ka corrosion.
9. Ka hopena
Hiki ke hilina'i 'ia ka hana anti-corrosion o na huila kila kila ma na kiwi hooki, aka, pili ia e na kumu he nui. Ma ke koho ʻana i nā mea kila kuhili ʻole kūpono, ka hoʻopololei ʻana i nā kaʻina hana lapaʻau ʻili, ka hoʻolālā kūpono a me ka mālama ʻana, a me ka hoʻohana ʻana i nā ala ʻike kūpono, hiki ke hoʻomaikaʻi maikaʻi ʻia kāna hana anti-corrosion no ka hoʻokō ʻana i nā koi o nā kiwi hoʻomaha ma nā ʻoihana like ʻole. I ka manawa like, me ka hoʻomau mau ʻana o nā kūlana ʻoihana a me ka hoʻomau mau ʻana o ka ʻenehana, ʻoi aku ka nui a me ka hilinaʻi o ka hoʻohana ʻana i nā huila kila kila ma nā kīwaha kū, e hāʻawi ana i nā hōʻoia ikaika no ka hana palekana o nā mea hana ma ke kahua o ka hoʻokele wai ʻoihana. Eia nō naʻe, ma ka hoʻohana maoli ʻana, pono nō e hana i nā koho kūpono a me ka mālama pono ʻana e like me nā kūlana hana kikoʻī e hōʻoia i kona hopena - lōʻihi a paʻa hoʻi.
